To all 4071.02. 1, it may, concern:

Be it known that I, Piiimrrn Ronnn'r, oi? 54 Rue Lepic, Paris, France, have invented certain new and useful lmpriwements in Heating Systems, of which the following is a specification.

This invention. has for its object an arrangement for generating pressure and maintaining the same in steam generators without the use of fuel and the invention may be applied for instance to the so-called mixed electric plants, comprising electric machines combined with hydraulic and. steam engines.

The particular object is to store in the form of heat aecmnulatcd in a steam generator or one or more thermic accumulators, the energy which has not been utilized during the working period of the machines ordinarily supplied with another source of power, the purpose of this being to restore at any required moment the energy or power thus stored and to utilize the same in order to operate the above mentioned machines.

N ow, the invention mainly consists in employing one or more tl'ie'rmio accumulators with an independent heating appliance such as a steam generator having electric resistances loaded with the excess, not utilized, of the current supplied by another source of power, as often happens in hydro-electric plants for lighting purposes or in power plants, the generator being in. such manner as to supply the accumulator by means of a circulating pump, so that it he comes possible to generate and maintain without the use of fuel the pressure in said. accumulator as well as in a steam generator or generators to which it is connected.

In the accompanying drawings, which are intended to show the invention applied to the generator plant of an auxiliary steam engine shop appertainingto an electro-hydraulic plant: Figure l is a side elevation the plant, Fig. 2 is a cross section or the same, Fig. 3 is a section through line 3 3 of Fig. 2, Fig. 4 is a plan view of part of the apparatus.

The generator lant has steam generators at Z) provided wit 1 a common supply pipe 0 said generators being connected with an accumulator o3 placed in proximity to steam generators 6 having electric resistances c. A circulating pump 1 is provided with suction pipe 9 which is connected on one hand by means otcoclr ii, to the pipe 7', leading from the lower part of the accumulator (Z and on the other hand by means of the cool: i to the pipe in, which can be connected, through cocks in, and a, respectively to the steam generators 'a and Z). The discharge pipe 0 of pump f communicates by means of a pipe 7) and a cock q with the lower part of the steain'gencrator c, and by means of a pipe 1* provided with cock 5, with the upper part of this steam generator on which is placed a cooler"; or the discharge pipe of the pump communicates with a pipe 11, leading to cocks o, m, placed at the lower part of the steam ,igc-nerators a and 7). J

The working is as follows: The steam generators a and Z), are filled up to a certain level, well as the accumulator (i, by means of supply valves placed at their upper side. During the night and during certain moments of the day, when the current supplied by the hydro-electrical station is not used in totality, the excess of the current is sent into the steam generator 0 having electrical resistances c for heating the water. Then the circulation pump f, is started, the cocks i, m, u and q heing open. The water sucked from the steam generators a and 5 through the pipe 71:, goes through the pump and passes out by the pipe p, flowing into the lower part of the steam generator 0, where it becomes heated. It leaves the upper part of the steam genei ator 6 through the cock 2 and pa ms in to the stean'i generators at and Z), 'ough the pipe u and the cooks o and :r. in us inside of the generators ct and 5 a circulation is established until the water contained therein reaches a temperature corresponding to the desired pressure. The cocks m, a, 2', 1;, o and a: are then closed thus interrupting all communication of the electrical steamgenerator c with the principal steam generatorsa and 6. Then the suction valve it of the pump is opened, as well as the cock 2 placed on the top part oi the electrical steam generator (2. The cold water is then drawn by the pump through the pipe j from the lower part of the accumulator d and is discharged. into the steam generator 6. From the steam generator c the heated Water passes hack to the accumulator through the coclr. 2 andthe pipe leading from the cock 2 to the top of the accumulator. This circulation in the accumulator is stopped when the water contained in the accumulator reaches a proper teuu'ierature. to send into the electrical steam generator 6,
